CTGrade rh IL-2 C126S

CTGrade rh IL-2 C126S

Part Number: 500-01

CTGrade rh IL-2 C126S is an immunomodulatory cytokine that is produced by lymphocytes. IL-2 signals through the IL-2R receptor to induce activated T cell proliferation and promote T cell differentiation. IL-2 also stimulates the proliferation and differentiation of B cells, natural killer (NK) cells, monocytes, and macrophages. CTGrade interleukins and growth factors are designed to support basic, translational, and clinical research, as well as commercial applications. *

Containing no animal-derived materials* human recombinant growth factors, CTGrade rh IL-2 C126S is produced in E. coli, is Beta-lactam-free and manufactured by Shenandoah in an ISO 9001:2015 certified facility that follows cGMP guidelines.

  • The core amino acid sequence and 126 C to S sequence of CTGrade rh IL-2 C126S are identical to Proleukin
  • Extremely low endotoxin levels
  • High biological activity verified by relevant bioactivity assay
  • Carrier Free protein
  • Available quantities: 50 µg, 100 µg, and 1 mg; custom sizes and packaging available
